The invention discloses an arrangement method of a spring tray of a torsion beam. The method comprises the following steps: S1: establishing a finite element analysis model of the torsion beam based on a three-dimensional model of the torsion beam; searching a low-stress area of a cross beam of the torsion beam in the finite element analysis model; wherein the maximum stress value on the cross beam is A, and the judgment condition of the low-stress area is that a low-stress area is formed in the area where the stress is less than or equal to k*A on the cross beam, and k is a low-stress coefficient and is less than or equal to 0.5, S2, setting a spring tray connected with the cross beam, and setting the connection position of the spring tray and the cross beam in the low-stress area. Therefore, forward research and development and structural design are carried out on the spring tray so that the connection between the spring tray and the cross beam is more stable and reliable; more importantly, through the arrangement method of the embodiment of the invention, multiple structural improvements on the sample piece of the spring tray in the research and development design process can be omitted, and the time cost and the labor cost in the research and development process and the machining cost for machining the sample piece for multiple times are reduced.
本发明公开了一种扭力梁的弹簧托盘的布置方法,包括:S1:基于扭力梁的三维模型建立扭力梁的有限元分析模型,并在有限元分析模型中查找扭力梁的横梁的低应力区,横梁上的最大应力值为A,低应力区的判定条件为:横梁上受力≤k×A的区域形成为低应力区,其中,k为低应力系数,k≤0.5,S2:设置连接横梁的弹簧托盘,将弹簧托盘与横梁的连接位置设置在低应力区内。由此,通过针对弹簧托盘的正向研发以及结构设计,以使弹簧托盘与横梁连接的更加稳定、可靠,更为重要的是,通过本发明实施例的布置方法,可以省去研发设计过程中,对弹簧托盘的样品件的多次结构改进,降低了研发过程中的时间成本、人力成本以及对样品件多次加工的加工成本。
